Was bedeutet der Fehlercode?
The LPG control module reads the front heated oxygen sensor while the car runs on gas. The sensor should switch evenly around the correct air-fuel ratio, and the code is set when it sticks at the lean limit for a longer time, meaning the fuel mixture is too lean.
Mögliche Ursachen
- Faulty vacuum hose linking the intake to the pressure regulator
- Blocked gas filter
- Incorrect gas pressure
- Fault in the wiring
- Defective fuel shut-off valve, or a shut-off valve on the engine or tank
- Defective pressure regulator or fuel rail
Was Sie tun können
- 1Make sure there is enough gas in the tank, since too little gas can cause the code
- 2Make sure the hose running from the intake to the pressure regulator is fitted properly and that fittings and hoses are sealed
- 3Have a workshop check the gas filter and replace it if needed
- 4Have a workshop check the gas pressure and the shut-off valves on the tank, the engine and the fuel rail
- 5Look for damage and chafing on the wiring and check that it has no breaks or short circuits
- 6If you have diagnostic equipment, run the car on gas and see whether the lambda value swings evenly; then erase the code and road test the car
Symptome, die Sie bemerken können1
- The engine does not run on gas
